[ 7] ABSTRACT Orally utilizable compositions which maybe either chewing gum compositions, chewable medicinal tablets, chewing tobacco or toothpaste having, on oral intake, a high flavor intensity release substantially evenly and uniformly, over an extended oral utilization time in the mouth cavity; the orally utilizable compositions containing a non-confined flavor oil, a flavor oil which is physically entrapped in solid particles and a suspending agent such as silica, xanthan gum and ethyl cellulose; the nonconfined flavor oil, the entrapped flavor oil and the suspension agent being premixed prior to addition to either of the chewing gum base, the chewing tobacco or the chewable medicinal tablet base, or to the toothpaste base.

6 Claims, No Drawings CHEWING GUM CONTAINING FLAVOR COMPOSITION BACKGROUND OF THE INVENTION This invention relates to improved orally utilizable compositions having a flavor with good initial strength and which flavor is controllably released (under the hy-' drolytic conditions of the human mouth cavity) at a consistently high level over an extended period of time;

to processes for preparing such orally utilizable compositions; to flavor compositions useful in preparing same and to processes for preparing such specially useful flavoring compositions.

The term orally utilizable compositions includes such materials as chewing gum, chewable medicinal tablets such as chewable vitamin tablets, chewing tobacco and toothpaste.

There has been considerable work performed relating to orally utilizable substances such as chewing gum,

chewable medicinal tablets, chewing tobacco and toothpaste whereby such orally utilizable substances have a flavor impact both initially and over an extended period of time. Problems have arisen in attempting to create such orally utilizable compositions wherein part of the flavor is available for immediate results whereas another part provides the effect of such flavor gradually over extended periods of time. Such problems include the continuous distribution of initial impact and extended release flavor over the entire mass of the orally utilizable composition as well as commercial manufacture of same.

U.S. Pat. No. 1,526,039, for example, teaches that if an essential oil or flavoring is combined with chewing gum base in a finely divided condition, and the particles of the flavoring or oil are encased in a suitable covering so as not to contact directly the gum during manufacture, the deleterious effect of the flavoring on the gum is prevented or largely reduced. It is further stated therein that:

When the emulsion is added to the gum base, it is thoroughly mixed therewith by the usual means employed for mixing the flavoring material with such base.

The production of the emulsion serves to break up the essential oil into fine particles and to encase these particles in the emulsifying material, so that when the emulsion is added to the gum mass, the essential oil to a large degree is prevented from coming into direct contact with the base, and from having deleterious action thereon.

U.S. Pat. No. 2,886,440 teaches a method of preparing a chewing gum characterized by extended flavor perception time, true flavor character, and high degree of flavor release comprising the steps of forming a spray-dried emulsion of a volatile, water-immiscible flavoring agent encapsulated within finely divided parfaster liberation of flavor and (ii) larger particles of gelat-in characterized by slower liberation of flavor, each of the gelatin particles containing dispersed therewithin, in dried emulsion form, discrete micro-droplets of a volatile water-immiscible flavoring agent, and an all-enveloping mass of a chewable gum base within which the particles are substantially uniformly distributed whereby the flavor is released substantially evenly and uniformly over the extended chewing time.

U.S. Pat. No. 2,886,445 teaches that:

It is possible to obtain a flavoring composition, particularly adapted for use in chewing gum which permits attainment of a product characterized by extended flavor perception time, true flavorcharacter, and release of a large proportion of flavoring agent. This flavoring composition comprises finely divided particles of adried hardened gelatin emulsion containing discrete micro-droplets of a volatile, water-immiscible flavoring agent. Preparation of. theflavoring compositionof this invention may be effected by encapsulating discrete micro-droplets of volatile, water-immiscible flavoring agent within finely divided particles of a dried emulsion of hardened gelatin. I

U.S. Pat. No. 2,886,449 teaches:

' A chewing gum containing a flavoring composition characterized by an extended flavor perception time,

true flavor character, controlled release of a large portion of flavoring agent, and reduction in amount of flavor oil required (which) may be prepared by the process comprising forming a gelatin-coacervated flavor, and substantially uniformly distributing said gelatincoacervated flavor within an all-enveloping mass of a chewable gum base. The product chewing gum comprises finely divided particles of coacervated gelatin containing a water-immiscible flavoring agent therewithin and an all-enveloping mass of a chewing gum base within which the particles are substantially distrib- I i uted.

The utilization of sustained released flavor containing capsules in such materials as chewing gum and medicinal tablets is also taught in British Pat. No. 1,205,764.

The use of sustained release flavor capsules in conjunction with polyethylene glycols (which are taught to be employed to disolventize the capsules) is set forth in British Pat. No. 1,318,799. However, the prior art does not set forth a commercially feasible process for creating an orally utilizable composition such as a chewing gum, chewable medicinal tablets, chewing tobacco or toothpaste containing a flavoring composition which provides instantanious, evenly distributed flavor release, extended continuous, non-interrupted flavor perception time periods and at the same time provides extended constant flavor impact during the period of time that said orally utilizable composition is used in the mouth; which is provided by our invention.

THE lNVENTlON This invention relates to improved orally utilizable compositions such as chewing gum, chewable medicinal tablets, chewing tobacco and toothpaste having a flavor with good evenly distributed initial strength and which flavor is controllably released with continuous non-interrupted high flavor impact over an extended period of time; to processes for preparing the same; to flavor compositions useful in preparing same and to processes for preparing such flavoring compositions.

Chewing gum and chewable medicinal tablets may comprise a substantially water insoluble, chewable, plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain comestible natural or synthetic resins or waxes. Incorporated with the gum base, and in intimate admixture therewith, may be plasticizers or softening agents, e.g., glycerine; flavoring agents, e.g., oil of Wintergreen, oil os spearmint, oil of peppermint, licorice, fruit flavors, spice oils, etc.; or sweetening agents which may be sugars including sucrose or dextrose and/or they may be artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.

Chewing tobacco may comprise specially grown tobacco for chewing which would include 85 percent Wisconsin Leaf Tobacco and percent Pennsylvania Leaf Tobacco having a casing" spray dried at a rate of about percent up to about 40 percent which casing would contain such ingredients as corn syrup, licorice, glycerin, fig juice, prune juice and as is the case in this invention, a flavor material. The resultant product is redried to a moisture content of between 10 and percent.

Toothpastes may comprise four groups of additives:

Group A: Glycerine; distilled water; sodium benzoate; if desired, artificial sweetner such as sodium saccharin and, if desired, stannous fluoride.

Group B: A basic pH buffer such as calcium carbonate and/or dicalcium phosphate.

Group C: A foaming agent such as sodium n-lauroyl sarcosinate.

Group D: A flavor material.

A standard technique for formulating the above groups into the toothpaste is exemplified as follows:

1. The ingredients in Group A are stirred and heated in a steam jacketed kettle to 160 F.

2. Stirring is continued for an additional three to five minutes to form a homogeneous gel.

3. The powders of Group B are added to the gel, while mixing until a homogeneous paste is formed.

4. With stirring, the flavor of D is added and lastly the foaming agent.

5. The resultant slurry is then blended for 1 hour. The completed paste is then transferred to a three roller mill and then homogenized, and finally tubed.

It is found that when most flavored chewing gums such as slab gums, and when most flavored chewing tobacco and chewable medicinal tablets are chewed and when most toothpastes are used in a normal toothbrushing procedure of 1-2 minutes, the initial perception of flavor appears after a minute or more at a low level, and after 3 or 4 minutes of chewing the flavor intensity drops to an uninteresting level. It is also found upon analysis in several instances that chewable medicinal tablets or chewing gum or tobacco chewed or toothpaste utilized for as long as thirty minutes may retain as much as 60 percent of the flavor initially presem, and that this part of the flavoring agent is thus not effectively used.

it is an object of this invention to provide an orally utilizable composition containing a flavoring composition characterized by (i) an almost instantaneous flavor perception and (ii) over an extended period of time controlled constant and continuous, non-interrupted, I

high impact flavor release.

A second object of this invention is to increase the total amount of flavor released during the chewing period of chewing gums, chewing tobacco and chewable medicinal tablets or during the toothbrushing period of toothpastes containing the herein described flavoring composition.

Other objects of this invention will be apparent to those skilled in the art from the following detailed description of the invention.

It has now been discovered that it is possible to obtain an orally utilizable composition, such as chewing gum, chewable medicinal tablets, chewing tobacco and toothpaste containing a flavoring composition which provides almost instantaneous flavor release, extended high intensity constant flavor perception time, true flavor character and controlled release of the major proportion of flavoring agent initially present in the flavoring composition. This flavoring composition of our invention consists essentially of:

a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil;

b. From about 3 up to about 7 parts by weight of a hydrolytically releasable flavor oil physically entrapped in an edible solid material, said solid material having a particle size of from about 5 microns up to about 400 microns said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; and

c. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of colloidal silica, xanthan gum and ethyl cellulose having a particle size of from about 0.008 up to about 0.030 microns, a surface area of from about up to about 400 m lgm and a density of from about 2.0 up to about 3.0 lbs/cu.ft.

Preparation of the flavoring composition employed in the orally utilizable compositions, of our invention may be effected by:

l. Admixing a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; and

b. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of colloidal silica, xanthan gum and ethyl cellulose having a particle size of from about 0.008 up to about 0.030 microns, a surface area of from about 150 up to about 400 m /gm and a density of from about 2.0 up to about 3.0 lbs/cu.ft., thereby forming a first suspension; and then 2. Admixing said first suspension with from about 3 up to about 7 parts by weight of a hydrolytically releaseable flavor oil physically entrapped in an edible solid material, said solid material having a particle size of from about 5 microns up to about 400 microns thereby forming a second suspension, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil.

The orally utilizable composition of our invention such as chewing gum, chewable medicinal tablets, chewing tobacco, and toothpaste may be prepared by the steps of:

l. Admixing a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; and

b. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of colloidal silica, xanthan gum and ethyl cellulose having a particle size of from about 0.008 up to about 0.030 microns, a surface area of from about 150 up to about 400 m /gm and a density of from about 2.0 up to about 3.0 lbs/cu.ft., thereby forming a first suspension (if desired an additional product stabilizer such as propylene glycol may also be incorporated into the mixture);

2. Admixing said first suspension with from about 3 up to about 7 parts by weight of a hydrolytically releasable flavor oil physically entrapped in an edible solid material, said solid material having a particle size of from about 5 microns up to about 400 microns (preferably from 70 up to 300 microns) thereby forming a second suspension, said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; and

3. Substantially uniformly distributing said second suspension with an all-enveloping base selected from the group consisting of l chewing gum base, (2) chewable vitamin tablet base, (3) chewing tobacco, and (4) toothpaste base, depending upon the ultimately desired orally usable composition.

The solid physical entrapment material used to entrap the hydrolytically releasable flavor oil may be of various convenient physical shapes, e.g., capsules having gelatin shells; particles of dextrin and/or modified food starch and/or gum acacia capable of adsorbing and/or absorbing and retaining flavor oils until exposed to the hydrolytic conditions of the human mouth.

The gelatin which may be employed in this invention may be any of the grades and types of gelatin, including those obtained from e.g., tanners stock, ossein, pigskin, etc. The Bloom of the gelatin which is employed may vary widely, although a particularly rapid release from that portion of the flavor which is physically entrapped may be obtained by use of gelatin having a Bloom of about 50 or less, the Bloom may be as high as 200 or even higher. Although the pH of the gelatin solution employed may fall within the range of 2 to 10, it is preferred that it be maintained in the acid region, e.g., 2 to 5.

ln carrying out the process of our invention, sustained release flavors are prepared by combining nonconfined flavor oils with encapsulated or physically entrapped flavor oils. These combinations are fashioned so that the free oil is bound in a network of physically entrapped flavor and suspending agent.

Acacia may be replaced with various modified food starches, such as Capsul manufactured by the National Starch and Chemical Company of New York, New York, or dextrins such as Schardinger Dextrins produced according to Example 1 to 14 of US. Pat. No. 3,472,835 issued on Oct. 14, 1969; or such dextrins as Nadex manufactured by the National Starch and Chemical Company of New York, New York. The physical forces of these modified starches or dextrins are different from those of acacia, so that when such formulations as the above formulation are prepared using a modified starch or dextrin (entrapped flavor oil a thin rapidly separating unstable mixture results. This difficulty is corrected, however, by making adjustments in the formulation by adding low molecular weight polyhydroxy alkanes such as propylene glycol to modify the physical forces of the system.

The following composition, for example, where modified starch is used as the physically entrapment material forms a stable product:

Parts by Weight Ingredient Oil of Peppermint 47.25 Physically entrapped Peppermint 47.25 oil produced by the spray-drying of an emulsion of modified starch,

peppermint oil and water Cab-O-Sil M-5 5.00 Propylene Glycol 0.50

Ingredient Parts by Weight (a) Peppermint Flavor I Non-confined oil of peppermint Cab-O-Sil M-5 Physically entrapped peppermint oil produced by spray drying an emulsion of gum acacia, peppermint oil and water.

(b) Cherry Flavor Non-confined cherry flavor 26 Cab-O-Sil M-5 9 Physically entrapped cherry 6S flavor produced by spray-drying an emulsion of modified food starch. cherry flavor and water.

These flavors have an appearance identical to standard, commercial spray dried flavors but have much more aroma resulting from the presence of the nonconfined flavor oil portion which is mixed with the 7 physically entrapped, e.g., spray dried, or encapsulated portion.

The value of using these sustained release flavors, in orally utilizable compositions such as chewing gum and chewing tobacco, other than the fact that they provide ease and convenience when used in flavoring products,

as compared to adding a free flavor oil portion and an encapsulated flavor oil portion separately is:

A. The non-confined flavor oil is not free in the flavor composition of our invention release form; but it is bonded by physical forces in a network with the physically entrapped or encapsulated oil and suspension agent, and is therefore highly protected from its environment compared to the case of a non-confined flavor oil by itself; and

B. A more uniform distribution of flavor exists as compared with a product created by means of the separate addition of (i) liquid non-confined and (ii) dry physically entrapped flavor components.

In the case of powdered flavor mixes which contain physically entrapped, e.g., encapsulated flavors that are reconstituted before use, sustained release flavors are also of value. Encapsulated flavors have very little aroma; only that aroma evolved from the residual oil which is not enrobed. A jar of cherry flavored drink powder while having the proper amount of flavor when reconstituted, from its encapsulated flavor, lacks suitable jar aroma when opened by the consumer. The use of the dry sustained release cherry flavor of our invention provides the drink mix with good jar aroma as well as the proper flavor when reconstituted.

In carrying out one particular aspect of the process of this invention, a solution of physical entrapment agent, e.g., gelatin, modified food starch, dextrin, or gum acacia, may be formed containing to 100 parts of entrapment agent per one hundred parts of water, the latter being preferably at a temperature of 90 F. to 180 F. during dissolution of the entrapment agent.

The solution is allowed to cool preferably to 33 F. to 75 F., and it is then solidified by spray-drying.

Prior to the spray-drying of the solution of entrapment agent and preferably after cooling to 80 F. to 140 F., the desired volatile, water-immiscible flavoring agent may be added to the solution and homogenized to form an emulsion. The flavoring agents which may be employed include oil of peppermint, cherry flavor, orange oil, lemon flavor, lime flavor, oil of spearmint, fruit essences, licorice, spice oils and the like. The selected flavoring agent may be added in an amount equal to 10 to 100 percent of the weight of the entrapment agent. Examples of the physically entrapped flavor material utilizable in our invention are:

' Cherry flavor oil physically entrapped in dextrin;

. Cherry flavor oil encapsulated in gelatin capsules;

. Cherry flavor oil entrapped in gum acacia;

. Lemon flavor oil physically entrapped in dextrin;

. Lemon flavor oil encapsulated in gelatin capsules;

Lemon flavor oil entrapped in gum acacia;

. Lime flavor oil physically entrapped in dextrin;

. Lime flavor oil encapsulated in gelatin capsules;

i. Lime flavor oil entrapped in gum acacia;

j. Peppermint flavor oil physically entrapped in dextrin;

k. Peppermint flavor oil encapsulated in gelatin capsules;

l. Peppermint flavor oil entrapped in gum acacia;

m. Oil of Wintergreen physically entrapped in dextrin;

n. Oil of Wintergreen encapsulated in gelatin capsules;

0. Oil of Wintergreen entrapped in gum acacia;

p. Orange flavor oil physically entrapped in dextrin;

q. Orange flavor oil encapsulated in gelatin capsules;

r. Orange flavor oil entrapped in gum acacia;

5. Cherry flavor oil entrapped in modified food starch;

t. Lemon flavor oil entrapped in modified food starch;

u. Lime flavor oil entrapped in modified food starch;

v. Peppermint flavor oil entrapped in modified food starch;

w. Oil of Wintergreen entrapped in modified food starch; and

x. Orange flavor oil entrapped in modified food starch.

When the emulsion of flavoring agent in solution of entrapment agent is solidifed as by spray-drying the resultant spray-dried emulsion may have the flavoring agent in the form of discrete micro-droplets encapsulated in very fine particles of dried gelatin or it may have the flavor oil absorbed into solid particles as is the case with gum arabic or gum acacia. The solid spraydried emulsion will be in powder form which may be 5 microns to 400 microns. The preferred size being -300 microns.v

Formation of a flavored chewing gum, for example, may be effected by:

l. Admixing a. From about 3 up to about 7 parts by weight of a non-confined hydrophobic flavor oil; and

b. From about 0.1 up to about 1 part by weight of a solid suspending agent selected from the group consisting of colloidal silica, xanthan gum and ethyl cellulose having a particle size of from about 0.008 up to about 0.030 microns, a surface area of from about up to about 400 m /gm and a density of from about 2.0 up to about 3.0 lbs/cu.ft., thereby forming a first suspension;

2. Admixing said first suspension with from about 3 up to about 7 parts by weight of a hydrolytically releasable flavor oil physically entrapped in an edible solid material, said solid material having a particle size of from about 5 microns up to about 400 microns thereby forming a second suspension said physically entrapped flavor oil being organoleptically compatible with said non-confined hydrophobic flavor oil; and

3. Substantially uniformly distributing said second suspension within an all-enveloping mass of a chewable gum base.

A preferred composition has 0.5-3.0 percent of flavoring composition in 97-995 percent by weight of gum base, more preferably, 1 percent flavoring composition: 99 percent gum base. Typically the gum base will be chicle, although it may be jelutong, guttakay, etc. Other ingredients including sweetening agents, coloring agents, etc. may be present in desired amount.

Although the orally utilizable compositions of this invention be prepared from a single flavoring agent, e.g., cherry flavor, it is possible to extend the rnage of properties of the gum by use of combinations of two or more spray-dried flavoring compositions and two or more non-confined flavors which may or may not be different but which are organoleptically compatible with the physically entrapped flavors. For example, it is possible to separately prepare spray-dried flavoring composistandard gum, and the flavor rapid release). The properties of the chewing gum product will be intermediate to the properties obtained from each of the flavoring compositions when used separately. Specifically, if a flavoring composition formed from 50 Bloom gelatin is mixed with a flavoring composition formed from 200 Bloom gelatin, and the mixture vigorous mouth use for extended periods which may be is both (i) added to a flavor oil and suspension agent which composition is added to chewing gum and (ii) added to a chewing gum alone, the product may have a flavor release which is substantially more even over the chewing period than is the case when a single flavoring composition just containing the entrapped and nonconfined flavor oil and suspension agent is employed.

Similarly, it is possible to modify the properties of the product gum by use of mixtures of spray-dried flavoring compositions characterized by different ratios of entrapment agent to flavor oil. If, for example, a composition containing 10 percent flavoring agent and 90 percent gelatin is mixed with one containing 50 percent flavoring agent and 50 percent gelatin the resulting blended flavoring composition, after adding non-confined flavor oil and suspension agent, will yield a chew ing gum having a more even (relating to duration of chewing time) liberation of flavor than is obtained by use of either flavoring agent alone. i

Liberation of flavor of the orally utilizable composition of this invention may also be modified in a controlled manner to obtain an even, sustained flavor level from the time that use (e.g., chewing) in the mouth begins and thereafter for a protracted period of time far in excess of that obtained today in any such chewing gum, chewing tobacco, chewable medicinal tablet or toothpaste, by, using various mixtures of flavoring compositions (a) having different particle size of physically entrapped flavor, (the resulting product deriving much of its initial flavor from the smaller particles and much-of its later flavor from the larger particles); or (b) formed :vention contains unflxed flavor, spray-dried flavor, and

suspension agent in proportions of about-1:1:0.1. This product is characterized by an interesting or pleasing flavor level which may start at 0.25 seconds and last for 27-28 minutes. Over substantially its entire period of flavor release, the flavor level is higher than that of the is continuous, rich, full,

and true.

It is particularly characteristic of the orally utilizable compositions of this invention, that they have almost instantaneous to very early flavor perception when more than 0.25 seconds when orally utilizable compositions are prepared in accordance with this invention. Prior art chewing gums containing only free unfixed flavor have initial flavor perception after 4-5 seconds and frequently after times as long as one minute.

used in the mouth. Usually flavor is apparent in not It is also characteristic or our orally utilizable compositions that they retain the flavors under conditions of triple that of compositions heretofore known to those skilled in the art. For example, the flavor perceptiontime may be as long as twenty minutes, in contrast, to

the usual 3-10 minutes which is the flavor perception time of comparable products heretofore known (e.g.,

US. Pat. No. 2,886,440). g

The greater availability of flavor ing compositions herein described also permits attainment of high flavor level in the orally utilizable composition with use of lower amounts of the flavoring oils.

Orally utilizable compositions prepared with the flavor composition in accordance with this invention,

have a flavor character more nearly that of the original flavor oil than chewing gum prepared by merely the direct incorporation of the flavoring oil into the chewing gum without concomitant use of thephysically en- I trapped flavors'and suspension agents.

The term encapsulate may be used to describe the distributed substantially uniformly within or in the interstices of finely divided particles of the former. The flavoring agent is locked in within the entrapment agent (e.g., gelatin, gum acacia, dextrin and modified food starch to the extent that the former is released substantially only as the molecules of entrapment agent i are dissolved from the surface of the individual entrapliquids.

EXAMPLE W A. PREPARATION OF LEMON OIL CAPSULES PREPARATION OF THE SHELL COMPOSITION AND SOLUTION Five hundred grams of water are heated to boil and 500 grams dextrin (National Starch and Chemical Corporation, 78-1523) is added with rapid and efficient mixing, using a closed turbine, high shear mixer (Barrington CONVERTI JET Model CJ-SB). Mixing is continued until a homogeneous solution is obtained. B. PREPARATION OF LEMON OIL CAPSULE COMPOSITION 81 grams of lemon oil (California cold pressed oil) is emulsified in 300 grams of the shell composition solution (A) by means of a homogenizing mixer (Barrington CONVERTI JET Model CJ-SB operated as a closed turbine unit). At the start of the operation the temperature of the matrix composition solution is 20 C and. of the lemon oil 15 C. The mixing vessel is cooled during the operation of the mixer in order to prevent a rise in the temperature and to keep the temperature below 25 C. C. CAPSULE FORMATION AND DEHYDRA- TION One thousand grams of polyethylene glycol having an average molecular weight of 400 (Union Carbide Corporation, Carbowax 400) and at a temperature of about 25 C is placed in a vessel equipped with a homogenizing mixer (Barrington CONVERTI JET Model CJ-SB operated as an open turbine unit). One hundred grams of the lemon oil capsule composition (B) is introduced into the polyethylene glycol in a thin stream with steady medium speed operation of the mixer (about 1,500 rpm shaft speed). By the action of the mixer, the lemon oil emulsion is broken up into coarse liquid particles, which in contact with the polyethylene glycol, are rapidly converted into gel particles and tinally into virtually anhydrous capsule granules.

The capsule granules are separated from the excess EXAMPLE I The following mixture is prepared:

A taste test is made to compare the chewing gum products of this invention of Examples XXII XLII inclusive with (i) standard chewing gum containing the same total amount of alvor in unfixed form and (ii) chewing gum containing the same total amount of flavor without the Cab-O-Sil or ethyl cellulose or xanthan gum and with each flavor ingredient (fixed and unfixed) added to the chicle spearately rather than in a blend. During the test, 1.0 inch X 3.0 inch X 0.1 inch slabs of each gum are separately chewed and the following noted: Time and intensity of initial flavor, extent of flavor burst, duration of interesting flavor level, and approximate total time during which flavor is available.

In these tests, the rating of flavor intensity is measured by the person chewing, on a scale ranging from to 10, the level of 1 indicating threshhold flavor intensity just discernible to the taste, and a level of indicating a maximum intensity above which the sensation originating in the flavor is unpleasant.

The commercially available standard (i) containing unflxed flavor in chicle is characterized by initial indication of flavor at a level of 1 after about 78 seconds. Intensity rises to 3 at about seconds, and thereafter at a slower rate to a level of 6 at about 60 seconds. At this point, flavor intensity drops off to 3 after about 90 seconds. At about 2 minutes, the flavor intensity is at the uninteresting low level of 1.5. After 4 minutes of chewing, the flavor drops below the threshhold value of 1, and the standard gum (i) is flat and lifeless.

The standard (ii) containing flavor in both fixed and unfixed form but without the Cab-O-Sil or ethyl cellulose or xanthan gum and with each flavor ingredient (fixed and unfixed) added to the chicle separately rather than in a blend, is characterized by initial indication of flavor at a level of 3 after 78 seconds with intensity rising to 6 at about 20 seconds and thereafter at a slower rate at a level of 7 at about 60 seconds. At this point, the flavor intensity drops off to about 5 after about seconds. At about 4 minutes, the flavor intensity is at the uninteresting level of 1.5. After 8 minutes of chewing, the flavor drops below the threshhold value of 1 and the standard gum (ii) is flat and lifeless.

Samples prepared in accordance with the invention as set forth in Examples XXII XLII, supra, are found to have an initial flavor liberation which occurs substantially immediately (at about 0.25 seconds) i.e., more quickly than does that of the standard or (i) or (ii), and which is at a higher level than that of either standard. The flavor or intensity of the chewing gum product of this invention continuously rises to a high level which is four fold that of the maximum level reached by the standard (i) and twice that of the maximum level reached by the standard (ii) and it remains at this high level for a total period of time which is four fold the total flavor perception time of the standard (i) and twice the total flavor perception time of the standard (ii). Under preferred conditions, flavor liberation is apparent for a time which approaches 20 minutes. During the entire chewing period, which is typically 24 times as long as the chewing period of either standard chewing gum, the flavor of the product of this invention may be found to be rich, full-bodied and substantially true in character.

It will be apparent to the person making the chewing test that the chewing gum samples prepared in accordance with this invention are eminently superior to the samples containing the same amount of flavoring oil in unfixed form alone or the chewing gum containing the same total amount of flavor without the Cab-O-Sil or ethyl cellulose or xanthan gum and with each flavor ingredient (fixed and unfixed) added to the chicle separately rather than in a blend. The extended flavor perception time, early flavor release, true flavor character, and high degree of released flavor make this new product superior.
